PROBLEM TO BE SOLVED: To provide a control method of an engine-driven air conditioner capable of solving a problem on the overflow of an accumulator, and using a low-pressure switch for an expensive low-pressure sensor. SOLUTION: The engine is stopped in any case of a case when a pressure of a refrigerant high-pressure line becomes more than a predetermined second predetermined pressure, after an expansion valve 9 is completely closed, and a liquid flow rate adjusting valve 14 is completely closed in stopping the cooling/heating operation , a case when the low-pressure switch 18 is turned OFF, a case when a second predetermined specific time has passed after the liquid flow rate adjusting valve 14 is completely closed, when more than the predetermined first predetermined time has passed after the start of the air conditioner, and a case when the second predetermined specific time has passed after the liquid flow rate adjusting valve 14 is stopped, when the operation time after the start of the air conditioner is less than the first specific time.
